BTC.D Weekly. Decreasing to correct on support?

Bitcoin dominance. Approaching support ( green horizontal line ) and may, if support reached start to correct from the downwards impulse. Dominance had hitherto been in a neat, well defined bullish ascending channel. The orange circle on a similar move is an example of the type of correction we may see soon. Retrace target is the dashed line.

If Bitcoin dominance increases to the target the green arrows direct to then we my get some useful Alt buying opportunities.
